Question
What do my viral load test results mean?
5 January 2016. Related: All topics, CD4 and viral load.
Please can you explain how viral load results mean?
I got my results back and I don’t understand them. It says log units is 2.777 and my RNA copies is 599 cp/mL.
Is this low or high? My CD4 count is 697.
Answer
Hi
Thanks for your question – and it is good that you want to understand your test results.
Sometimes this can be dfficult if your doctor has not explained them clearly. It is also okay to ask your doctor or nurse to explain anything that you are not sure of.
Viral loads tests tells you how much virus is in a millilitre of blood (or another body fluid being measured).
When not on treatment, viral load can range from undetectable to several millions. For anyone on HIV treatment (ART), viral load should ideally get to undetectable, This is defined as being less than 50 copies/mL.
Your test results are the 599 copies/mL, so your viral load is still detectable at 599.
The ‘2.777 log units’ from your test results is a slightly complicated way of saying exactly the same thing as ‘599 copies/mL’.
Because viral loads have such a huge range of numbers they are sometimes expressed in ‘log units’ to make it easier to write them on graphs and diagrams. Doctors and scientists use log scales to look at changes to viral loads over time. See this table of log units compared to viral loads in copies/mL.
Whether this is considered high or low depends on whether or not you are on treatment.
- If you’re not on treatment yet this is a relatively low viral load, which is a good thing.
- If you are on treatment, then if you only recently started ART, your viral load might still be going down.
- If you have been on treatment for more than six month, please talk to your doctor about why the results in not undetectable.
For more information about viral loads and how they relate to both treatment and infectiousness you can also have a look at the following links:

If you tell me if you are currently on treatment or not I can provide more individual information, Also, if you are on treatment, when did you start?

Hi Kitty,
Please see the above post, this explains what viral loads means. For reference you’re is undetectable, which is great news
If CD4 count is 224 and viral load is 20, is there any decrease of HIV disease in my body?
Hi i,

Have sex with HIV POSITIVE person and use a condom on her what is the risk?
Hi Ella,
Do you know when your daughter took PrEP, was it within 72hrs of sexual intercourse? If it was then there is a high change that your daughter will be OK.
You mention viral load, a viral load is a blood test that is used when looking at a persons HIV. If its high then this means that a person is HIV positive. Are you sure that your daughter said she had a high viral load? Also, has your daughter done a HIV test yet?
My daughter was exposed to the HIV virus, but she said her doctor gave her PrEP. Does this mean she has HIV? She says her viral load is high, will this medicine keep her from becoming HIV positive?

Hi Mankidi,
What ARVs are you taking? Have you always been on the same ones? Do you take them daily as prescribed?
When you say that your viral load changes, how much does it change by? Is this something that you have talked to your doctor about?
Hi,ive been on ARVs since 2009 now and im sexually active but my viral load always changes n i always use a condom. I exercise at least 3 to 4 times a week. What might be the cause of it dropping sometimes?
